I wouldn't spend $180 on that. Problem with a brake style like that is that you can't shoot it prone without blowing everything off the ground around the muzzle. Harrell's makes a brake just like that for $30 and you can usually have them installed for $80

If you plan on shooting prone you will want to go with a slotted brake. You can get a muscle brake installed for about the same price as the turbo brake.
